- Expert Description
- En: An active buffer with a phase splitter rather than a transformer, drawing 5 mA from 48 V phantom. Two operating states are published side by side throughout the table: input impedance 800 kohm / 23 kohm, maximum input +2 dBu / +8 dBu, clip level +3.3 dBu / +12.3 dBu, gain +1.3 / +4.4 dB. · Uk: Активний буфер із фазорозщіплювачем замість трансформатора, споживає 5 мА від 48 В фантомного. Уся таблиця подана двома станами поруч: вхідний опір 800 кОм / 23 кОм, максимальний вхід +2 dBu / +8 dBu, поріг обмеження +3,3 dBu / +12,3 dBu, підсилення +1,3 / +4,4 дБ.·

What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
Named like something else
«Gain: +1.3dBu/+4.4dB»
The two halves of this gain figure carry different units. dBu is an absolute level referenced to 0.775 V, so a gain — a ratio between two levels — cannot be expressed in it; the second half, in dB, can. Read against the neighbouring rows (Maximum Input +2 dBu / +8 dBu and Clip Level +3.3 dBu / +12.3 dBu) both numbers behave as gains of 1.3 dB and about 4.3 dB, which is what the row appears to mean.
